If you just want to add a set number to another number in an int field, maybe just choosing the right generator, using a custom generator, or a python generator will do the trick. Provided you don't want to add two numbers from two columns in the same table. That's still a problem for SDG. If you can be a bit more specific I can give some advice about how to do it.

Ben's done a plugin for SDG that will allow you to do this, but I'm not sure it will work in v2:
http://www.simple-talk.com/dotnet/.net- ... generator/ SQL Data Generator v2 has Python script embedded in it, but the config object only seems to pass data from the column that is currently being generated and you don't have access to other columns. Not sure why it has this shortcoming...

Exactly. I have spent some time looking at possible python scripts usage and I miss some functionalities...
I will be evaluating the IronRuby generator in the next couple of days - will let you know if that works.
Thanks for the reply anyway.

I know you don't support the IronRuby stuff - but could you provide me the step-by-step instruction of how to deploy Ben's generator into SDG? Which files need to be copy and where? I have 2.0.1.6 version.

Usually you just drop a custom generator dll into the SDG program files folder. SDG should reflect the namespace in the DLL and if it's correct, add it to a list of generators you can use. However, it may need to be recompiled for v2 if it doesn't work. Sadly, the SDG team chose not to document any of this, so I don't know exactly how it's meant to work.

When all the dll copied into SDG folder it results in a crash on generators' list open If you ever decide to adjust the generator for the SDG 2 - please post it somewhere. It looks like a really powerful iprovement towards complicated data validity. Would save my time on writing trigger and update scripts and running several projects...
